中国人,特别是汉族,历来都十分重视自己的姓氏,没有非常特殊的原因是不会改变的。但考察今天中国的姓氏分布可以发现,人口少的姓往往具有很强的地域性,只存在于某些地区,甚至只有一个地方才有。但人口多的姓却遍布各地,人口最多的几个姓甚至深入少数民族聚居区和海外。不过姓氏刚形成时,一姓一氏只限于具有共同血缘关系的宗族之间,分布范围不可能很广。不同的宗族采用同一姓氏的可能性虽然也存在,但毕竟有限。所以每个氏或姓都有自己的起源地,该姓氏的人口扩展到其他地方主要是迁移的结果。另一方面,汉族及其祖先华夏诸族有慎终追远的传统,只要有可能, Chinese, especially the Han people, have always attached great importance to their surnames. No very special reason is that they will not change. However, considering the distribution of surnames in China today, we can find that surnames with a small population tend to be highly regional and exist only in certain regions or even only one place.
